摘要
保定地区岩土工程勘察,应按地形地质状态分为山区,山前平原区,冲、洪积平原区三部分。山区勘察注意钻探结合物探方法,准确判定基岩的埋深及残积土的厚度;山前平原区注意上部土层往往有隐伏的古河道、古沟槽沉积,冲、洪积平原地层软弱,承载力不高,且夹层较多,注意取样数量及土工试验指标,满足计算要求。
Geoteehnical engineering investigation of Baoding area should be divided into mountain area, piedmont plain area, alluvial and flood plain area according to the topographic and geologic condition. When surveying mountain area, we should combine with drilling and geophysical methods to determine the buried depth of bedrock and residual soil thickness; when in piedmont plain area, we should pay attention to ancient river and ancient trench sedimentary; when in alluvial and flood plain, due to the soft ground, not high bearing capacity, and more interlayer, we should pay attention to sample quantity and soil test index to meet the requirements of calculation.
